... front curb side corner under the belly pan. I just was rewiring mine and good luck with getting the new pigtail through the frame. I ended up running it on the inside of the A frame and then into the belly pan. When you get in there you will find four thin red wires. They all look the same, but will have knots tied into them. I am not sure what the wire with no knot does, but the one wire with one knot is the left turn signal. Two knots is the right turn signal. Three knots is running lights. Re wiring the pigtail is a frustrating task. I had to pull my battery and make two leads as to test things as I went. Be sure to create a new ground wire while you are in there. With these 12 volt
systems you can never have it grounded enough.
